When the church ceases arguing and complaining, agape love is at work in us. The love of God will shine through us in the midst of a dark world. "By this all men will know that you are My disciples, if you have love for one another." John 13:35, also, I John 3:14 says, " We know that we have passed from death to life, because we love our brothers."
Shining as stars will signify that we have really come to a place of walking in genuine love. We no longer say things just because we think we have a right, but we speak and act in ways that is truly reflects our true image, which is of God in Christ Jesus.
I would say that complaining and arguing, behind the scene backbiting and the unspoken religious spirit at work has definitely had a negative effect on our church.
What I can do about it, is to not allow that kind of spirit affect my heart and pursue love above all.
